Officially there is no dipstick for the Q5.
I use 06J115611E that fits to MY2009-2012
I do not know which model fits for MY2014

I looked up the 2012, 2103, and 2014 oil filler tubes and they all have the same part number 06H-115-610E. So unless something has changed with the oil level in the sump of the new 2014 2.0T, then the 06J115611E should work just fine. I'm going to buy one and try it out.....
